NEW
GERMAN 42/28-MM AT GUN

A brief preliminary report has recently come in from an Allied source
concerning the new German small-caliber,
taper-bored 42/28-mm (1.65 in-1.10 in)
AT gun. This model has apparently made its appearance only this year, and in
small numbers. Its muzzle velocity is stated as 4,100 feet per second, which is
high for even so extreme a type of artillery. As will be noted from the
accompanying sketch, no muzzle brake is fitted, which seems rather odd in a weapon of
this type, but its absence would permit the use of spigot grenades. Further
details will be reported as soon as they are released, but the following are now
available:

This gun is mounted on the old-type 37-mm antitank gun mount, but is a
greatly improved antitank gun on account of its better penetration, due to its
stepped-up muzzle velocity. The walls of the breech have been reinforced. This
gun was manufactured at the Rhinemetall factory.
